示例 #1 Imagick::affineTransformImage()
<?php
function affineTransformImage($imagePath) {
$imagick = new \Imagick(realpath($imagePath));
$draw = new \ImagickDraw();
$angle = deg2rad(40);
$affineRotate = array(
"sx" => cos($angle), "sy" => cos($angle),
"rx" => sin($angle), "ry" => -sin($angle),
"tx" => 0, "ty" => 0,
);
$draw->affine($affineRotate);
$imagick->affineTransformImage($draw);
header("Content-Type: image/jpg");
echo $imagick->getImageBlob();
}
?>

This function is obsolete. Use distortImage() instead, with the affine transformation constant, and an array of six values, sx, rx, ry, sy, tx, ty.
